Nissan Repair: car problems, 2003 nissan altima, nissan altima

Question
my idel on my 2003 nissan altima goes up to 2000 then down to 1000 over and over again after a tune up


Answer
Hi Joseph -

Question - do you have the engine light on?

If you had the tune up done at a shop, I would definitely take it back and have them diagnose.

Otherwise, check the idle solenoid, the cold start valve to make sure all wires are connected to the terminals, as they could have dislodged during the tune up.

Hope this helps -
aloha
